Calibration Fluids for Temperature Calibration Baths

Information

Thermostatic baths / liquid baths / temperature calibration baths can be filled with three different types of substances:

  • Media that are in a liquid state at ambient temperature, such as oil, alcohol, mixtures with water-alcoholic base.
      
  • Biphasic fluids that turn liquid in a temperature field where the bath is expected to be used, composed of mixtures of potassium and sodium salts that are in a solid state at ambient temperature and that from about 150°C to about 500°C turn liquid and can be used as calibration liquids in specific thermostatic baths.
      
  • Other solid substances that - in specific conditions - turn to a state similar to the liquid state, for example sands or alumina powders with extremly thin granularitary that through an air insufflation in specific thermostatic baths behaves similar to a liquid.

LR-Cal  DRUCK & TEMPERATUR Leitenberger GmbH - in its standard temperature calibration baths - does not use biphasic fluids since, although their temperature field is very wide, they are very dangerous and ca cause explosions in particular working conditions.

LR-Cal  DRUCK & TEMPERATUR Leitenberger GmbH does not manufacture temperature calibration baths / thermostatic baths / liquid baths using alumina powders since it is not possible to completely eliminate the powders that are continuously discharged from the bath opering, causing therefore some problems as far as environmental compatibility is concerned.

The liquids, sold by LR-Cal  DRUCK & TEMPERATUR Leitenberger GmbH are mostly oils and glycol-based anti-freezing mixtures. The operating instruction of every single equipment contain an indication of the best liquid to be used for excellent performances.

*) Recommended usage field:
range of temperature in which it is possible to use the liquid in LR-Cal  baths, although the viscosity is not good to optain the best performances.
**) Temperature value above which an extractor hood should be used:
Temperature value above which an extractor hood should be used bcause the fume increases.
***) Fume burning point:
Temperature value on which steam triggers off in the presence of free flames.
****) Equivalent temperature for 10cst viscosity:
Temperature value below which the thermostatic performance is no longer excellent. The viscosity value tends to decrease as temperature increases. The equivalent water value at 23°C is 1cst
*****) Freezing temperature:
Temperature value below which the liquid changes its state and solidifies.

The calibration liquids are degenerated during usage. As higher the temperature and as longer the time of high temperatures, as faster is the degeneration of the fluid. For this reason: avoid high temperatures for longer times.
